NBC's decision to move The Apprentice back to Thursday paid off. Last night's episode — in which Bowie Hogg became the latest contestant fired by Donald Trump — attracted 18.7 million viewers. Last Wednesday opposite American Idol, The Apprentice sank to 12 million viewers. Speaking of The Donald, the king of self-promotion will spread his wealth of knowledge in a new book, How to Get Rich, due in April — coinciding with the show's live season finale.
